Signal Wiring
Signal wires are terminated with a telephone-type RJ14
connectors. Route the cable from the jack in the J-box to J6 on
the host driver (
). Run another RJ14 connector from J8
(Output) to the next (client) display, connecting at J6 (Input).
Follow this sequence to all displays in the sign network.

Address Dip Switch Settings
Every driver, either host or client, must have a unique address.
The address is set by pressing the individual toggle switches in
the eight-position dip switch case located on the driver (
).
The dark area shows that the switch has been pushed
down. In the example, switches 1 and 4 are on.
Addresses allow the user to set both line number (switches 1-3)
and sign number (switches 4-6) in as many as eight sign groups.
All displays with the same line number will show the same
price.
Refer to
Drawing B-256001
for an illustration of the client/host
driver setups and for a chart showing line number and sign
number settings for a large set of displays.
3.3 Power Up Self-test
Every time the display is powered up, it will run through a verification sequence. This is a
good way to check that the displays are set up and working correctly. The following items
will be shown on the digit displays. The second column explains the significance of each
item.
